The method includes: The first node sends a first instruction to the second node, where the first instruction is used to request storage location information of first data in the shared storage device, and the first data is data transferred by the second node to the first node for processing; and the first node obtains first information sent by the second node, and obtains mapping information from the shared storage device based on the first information, where the mapping information indicates a storage location of the first data in the shared storage device. The method is used to improve update efficiency of the database system, and ensure that different nodes can simultaneously process different data in a shared storage device.
